Should I remove any fan leaves or just leave them? Also, are the purple stems a sign of anything? I see differing opinions on the cause of purple stems, so I’m very curious. Ha. As always, thanks for any and all help!

Hey TryingToLearn,

Always good to defoliate but don't go crazy. I posted a video the other day but some might find it a little over aggresive :) Good general rule of thumb is, if it's covering a node, get rid of it. Strip the bottom third of the plant completely as this aids with airflow as well as send more energy to the upper areas and produce more A grade bud.

Purple stems can be natural or can also be signs of stress. PH fluctuations and temperatures are the usual suspects but could also be phosphorus or magnesium. Judging by the leaves on your plant, I'd say that your plants are probably hungry but it's pretty much impossible to diagnose from a few photos over a forum. I would take a step back and think about things. Here's I would go through things in my head in order.

How is the environment? Are things getting too hot or cold? What is the humidity right?

If thats all good, how about PH of the media? Take a slurry test and see what's going on at the rootzone.

Once you've checked and made any corrections there, move onto the feed. I know you have very low tapwater. Are you feeding enough or too much? Maybe you need to feed more or less? What are the manufacturers recommendations? Are you getting any tip burn? If so, you may have a lockout? Interveinal chlorosis? Could be underfed.

My advice would be not to correct individual micronutrient issues. You'll never 100% be able to diagnose without a tissue test and that level of testing isn't practical for the hobby grower.
Most base nutrient on thr market will provide adequate levels of macros and micros as long as you choose the correct feed for your water.

Hope this helps? Now my opinion looking at those photos is you have a few minor deficiencies with Mg being the main issue. Mg is low to non existent in your water, can cause the yellowing and red stems. My advice would to bring up the TDS of your water to ~150-200ppm with the magcal+ then give them a few feeds with food added. Others may have a different view but this is what I'm seeing. They don't look that bad btw just slightly hungry :)

Thanks for helping me out so much! I was definitely under feeding them. I was scared of feeding autos from what I had read online and was way under doing it. Hopefully with proper feedings now they’ll be alright and I’ll get some decent buds in the end.

Fed them today at lights on.

Fed them again today. Had to redo the post, because I didn’t like seeing my socks in the photos. Ha.

These are coming along real nice! Tight nodes on them, should be top to bottom colas in no time.

Love to hear that! I have no clue what to expect from these. Ha.

Keep an eye on that one with really dark leaves... If it starts to get tip burn I'd go water only a few times and then pick back up with feeding

Thanks! That’s exactly what I was thinking I needed to do, but was just guessing. Is it because that one was a weird runt seed, it needs less feed, and is starting to show signs of too much nitrogen and maybe other things?

Fed them again tonight.
